Make schedule available as iCalendar-download

[myabc]

An idea I discussed with @pietia – we enter schedule information into Lanyrd first, parse their .iCal files into our own Yaml format and display from there.

POC

# encoding: UTF-8
require 'bundler/setup'
require 'icalendar'

Encoding::default_external = Encoding::UTF_8

# Open a file or pass a string to the parser
cal_file = File.open("schedule.ics")

# Parser returns an array of calendars because a single file
# can have multiple calendars.
cals = Icalendar.parse cal_file
cal = cals.first

cal.events.each do |e|
  puts "- " << e.summary
  puts e.description
end
